E9–4941 Filed 3–13–09; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2008–1330; Directorate Identifier 2008–NM–138–AD; Amendment 39–15839; AD 2009–06–03] RIN 2120–AA64 Airworthiness Directives; Viking Air Limited Model DHC–7 Airplanes AGENCY : Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION : Final rule. SUMMARY : We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Transport Canada has received numerous service difficulty reports concerning Viking DHC–7 and Bombardier DHC–8 aircraft fluorescent lamp holder damage due to overheating. It has been determined that lamp holder overheating is a result of arcing between the fluorescent tube pins and the lamp holder contacts when the tube is not properly seated during installation. Overheating of lamp holders, if not corrected, could generate fumes and smoke * * *. * * * * * The unsafe condition could result in an in-flight fire. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES : This AD becomes effective April 20, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 20, 2009. ADDRESSES : You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

SUPPLEMENTARY INFORMATION : Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 23, 2008 (73 FR 78673). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Transport Canada has received numerous service difficulty reports concerning Viking DHC–7 and Bombardier DHC–8 aircraft fluorescent lamp holder damage due to overheating. It has been determined that lamp holder overheating is a result of arcing between the fluorescent tube pins and the lamp holder contacts when the tube is not properly seated during installation. Overheating of lamp holders, if not corrected, could generate fumes and smoke, causing concern to passengers and crew. This directive mandates repetitive inspection[s] for proper installation [and functioning] of fluorescent tubes and prohibits installation of non-arc-protected replacement fluorescent lamp ballasts. The unsafe condition could result in an in-flight fire. The corrective actions include replacing any lamps that are not properly seated in the lamp holder, and replacing any broken, non-functioning lamp holders. Replacing all affected fluorescent lamp ballasts would terminate the repetitive inspections. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use VerDate Nov<24>2008 13:57 Mar 13, 2009 Jkt 217001 PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 E:\FR\FM\16MRR1.SGM 16MRR1

11012 Federal Register / Vol. 74, No. 49 / Monday, March 16, 2009 / Rules and Regulations different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 21 products of U.S. registry. We also estimate that it will take about 1 work- hour per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $1,680, or $80 per product. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov ; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment ■ Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES ■ 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] ■ 2. The FAA amends § 39.13 by adding the following new AD: 2009–06–03 Viking Air Limited (Formerly Bombardier, Inc.): Amendment 39– 15839. Docket No. FAA–2008–1330; Directorate Identifier 2008–NM–138–AD.

SUPPLEMENTARY INFORMATION : Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing model 747–100, 747– 100B, 747–100B SUD, 747–200B, 747– 200C, 747–200F, 747–300, 747–400, 747SR, and 747SP series airplanes. That NPRM was published in the Federal Register on October 8, 2008 (73 FR 58901). That NPRM proposed to require inspecting for skin cracks at the shear tie end fastener locations of the fuselage frames, and repairing cracks if necessary. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Boeing concurs with the contents of the NPRM. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD affects 147 airplanes of U.S. registry. We also estimate that it takes 30 work-hours for the detailed inspection, or 49 work hours for the HFEC inspection, per product, to comply with this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $352,800 or $576,240, or $2,400 or $3,920 per product. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.
